Anarithma pamila is a species of sea snail, a marine gastropod mollusk in the family Mitromorphidae. ^[1]

Description

The length of the shell varies between 3.5 mm and 7 mm.

(Described in Latin as Anarithma sublachryma) The shell is smaller, biconical, and acuminated at both ends. The spire is short, rather solid, shining, and white, longitudinally veined with tawny between the ribs, and spirally trilineate (marked with three lines).

There are 9 whorls: the 3 embryonic ones are milky white, round, and smooth. The succeeding whorls are plano-declivous, scarcely convex, short, and adorned with strong, smooth longitudinal ribs. They are separated by a rather thick suture, with a single marginal furrow below the suture, and grooved with minute lirae between the ribs.

The body whorl equals 2/3 of the total length, is elongated, inflated superiorly, depressed in the middle, then striated, ending in a somewhat recurved and acuminated siphonal canal. The aperture is elongated, exceeding half of the total length, very narrow, and oblique. The columella is flexuous, concave superiorly, and unisulcate (one-grooved) in the middle.

The labrum (outer lip) is thickened at the suture, flattened, obliquely declivous, with an acute margin, sinuous below the suture, and then produced. In the aperture, it is thickened and plicate in the middle. ^[2]

Distribution

This marine species occurs off Papua New Guinea and New Caledonia
